Celluloid sheet material for table tennis

Abstract

The invention provides a celluloid sheet material for a table tennis. The celluloid sheet material comprises nitrocellulose, camphor powder, zinc oxide, acetic ester, a solvent, a flexibilizer, ethanol, acetone, a filling material, a coupling agent, and a pigment. The celluloid sheet material prepared by the formula has characteristics of high strength, good toughness, stable center of gravity, good elasticity, good ball sense responded from athletes, and high surface smoothness. Tributyl acetylcitrate is added into a conventional solution; the defect that the conventional solution is easily volatile is overcome; and the solubility and uniformity of nitrocellulose and camphor powder are further improved.

Description

technical field [0001] The invention relates to a celluloid sheet material, in particular to a celluloid sheet material for table tennis. Background technique [0002] Celluloid is the name of synthetic resin, which is the oldest thermoplastic resin in history, synthesized from raw materials such as nitrocellulose and camphor. Celluloid sheet material is a kind of material of making table tennis, and each table tennis manufacturer all adopts white match sheet as the material of making table tennis at present. The raw material of the white game sheet is heated and kneaded, filtered and discharged, rubber-mixed and calendered, hot-pressed, planed, dried, pressed, pressed and flattened to produce celluloid sheet for table tennis. [0003] The table tennis ball made of celluloid sheet material has disadvantages such as low strength, poor toughness, unstable center of gravity, poor elasticity, and players report poor ball feeling. Contents of the invention [0004] The main p...
